Notes * Cv values shown are for 2-way straight valve pattern. For 2-way angle patterns, increase CV value 50%. (Based on water). Formula for converting Cv to volumetric flow can be found in Technical Information section. ** Maximum Allowable Working Pressures decrease as temperatures increase - see pressure/temperature rating guide in Technical Information section.
Valve Packing Options
Standard Parker Autoclave Engineers valves with PTFE packing may be operated from 0°F (-17.8°C) to 450°F (232°C). High and Cryogenic temperature packing and/or extended stuffing box are available for service from -423°F (-252°C) to 1200°F (650°C) by adding the following suffixes to catalog order number:
- B Cryogenic trim materials and PTFE packing required when below 0°F (-18°C) to -100°F (-73°C)
- LT Extended stuffing box valve with PTFE packing and Cryogenic trim materials to -423°F (-252°C)
- TG Standard valve with PTFE-Glass packing -100°F (-73°C) to 600°F (316°C)
- GY Standard valve with Graphite Yarn packing 32°F (0°C) to 800°F (427°C). Used when selecting HT option.
- HT Extended stuffing box valve with Graphite Yarn packing to 1200°F (650°C)
